Sleep Apnea Detection

Abstract

Sleep Apnea Syndrome occurs due to the when the glands in the mouth relax further into the throat while sleeping causing blockage in the breathing passage resulting in pauses or apnea. This “pause” may last from 10 to over 30 seconds jolting the patient out of sleep. To detect if the person has apnea a sleep study known as polysomnography (PSG) is conducted in the hospitals where the patient stays overnight and the breathing pattern of the patient is studied. The Android application serves as a replacement of polysomnography, it allows users to monitor themselves in their sleep to detect sleep apnea. The system uses three sensors, a finger probe, a stretch sensor and a breath rate sensor. The android application is going to record these readings from hardware device to monitor patient during sleep. Android application is being developed using Eclipse and SDK 3.0.The recordings of all three sensors will be passed through the microcontroller over Bluetooth to the android application which will maintain graphs of these readings. When sleep apnea is detected the application sounds an alarm. It will also maintain the history of the patient which can be viewed by the doctor and will also detect how severe apnea is. The product will help out the sleep apnea patients to monitor themselves in sleep at their homes. It provides efficient, convenient and flexible sleep monitoring for personal use.
